I Have a Research Support System

On Thursday, Master Xu, who was busy with the decoration of Jiangwan's laboratory, began to concentrate on writing his two articles... Of course it is impossible.

As the small boss of the research group, all kinds of problems encountered by other members of the organic photovoltaic field will eventually fall on Xu Qiu's head.

On the way to Caiyi 216, Han Jiaying took the initiative to say: "Brother, I tried the fluorine reaction of thiophene before, but the fluorine atom couldn't go up."

"Is it a reaction to synthesize PBDB-T derivatives?" Xu Qiu asked.

"Hmm," Han Jiaying nodded, "We need to connect fluorine atoms to the thiophene unit of BDT."

Xu Qiu thought for a while and said, "I remember that the photoelectric company in Shencheng has ready-made monomers that can be purchased, and the H3x system used the fluorinated BDT unit before."

"That's right, but I bought 200 mg before, which is only enough for two reactions, and it has long been used up." After a pause, Han Jiaying explained:

"I wanted to buy some more this time, but they said they were out of stock. If I want to buy them, they have to make them for us, and they only sell for 1 gram. However, 1 gram of fluorinated BDT units costs 9,000 yuan, and ordinary BDT units 1 gram only sells for about 1,500, which is as much as six times worse, so I planned to try to synthesize it myself, but found that the fluorine atoms couldn’t go up.”

"It's expensive. There must be a reason for it. Most likely it's because the synthesis is difficult and the yield is low. Well, let me ask you when I get to the office." Xu Qiu replied.

When the two arrived at the office, Xu Qiu turned on the computer, retrieved the product catalog of Shencheng Optoelectronics, and found the serial number of the fluorine-substituted BDT monomer, which was BDT42. The BDT unit of the chain is numbered BDT43.

Xu Qiu logged into QQ, contacted sales, and sent a message: "BDT42 and BDT43 each buy 200 mg, urgently needed."

After a few minutes, I received a reply: "I'm sorry, these two monomers are temporarily out of stock. If you want them, we need to arrange a special person from our company to synthesize them. They can be sold from 1 gram."

Seeing this, Han Jiaying gave her a "Look, I'm right" look.

Xu Qiu was unmoved, and continued to send messages: "We are from Wei Xingsi's research group. This year, we have published several articles on NC, AM, AEM, and EES. Your company name is listed in the experimental details. Customers are attracted, and 200 mg is only a preliminary trial, if the effect is good, they will continue to buy."

Xu Qiu was not cheating on the other party. He asked them to send a batch of polymer donor samples, and later bought back the PTAZ and P3TEA donor materials.

After waiting for more than half a minute, the salesperson replied: "I just checked the historical records, it turned out that it was you, and I can help you."

It's been a long time since Xu Qiu contacted the sales of this Shencheng Optoelectronics company. Usually, Han Jiaying or Chen Wanqing would do it for him when buying materials here. Now it seems that his name is still useful.

Sales: "For 200 mg, BDT42 is 2200, and BDT43 is 2400. This is already the most favorable price. If possible, I will ask my colleagues in the synthesis department to help you."

Xu Qiu: "Yes."

Sales: "By the way, is there any new news in your group recently?"

Xu Qiu: "Well, the article has just been submitted. After a while, when the article is published, I will give you a copy of the PDF. It is not convenient to reveal too much at the moment."

Sales: "Understood, I have already arranged those two materials for you, and they will be synthesized next week and shipped to you as soon as possible."

Sales: '[image]'

Sales: "We have launched a new customer feedback activity this year. For articles published in SCI Districts 1 and 2 after January 1 this year, as long as the experimental details mention that the drug was purchased from our company, you can apply for it. Receive bonuses, including 10,000 yuan for CNS articles, 1,000 yuan for articles in the first district, and 500 yuan for articles in the second district, and the articles must be published this year to apply.”

Xu Qiu: "Then let me count."

Xu Qiu opened the homepage of Wei Xingsi's research group. According to Teacher Wei's request, the information on this homepage must be updated in real time as long as there are new articles published. According to Teacher Wei, "Only by decorating the front can attract talents. Come and run."

I don’t know if I don’t count the statistics. I was surprised by the statistics. Xu Qiu found that there are really a lot of articles this year. Except for the PCE11 AM which was published years ago, other PCE11 derivatives, 3D-PDI, and the ADA of the senior sister Acceptor materials were published after the year.

In total, there are three ACSAMI, one JMCA, two AEM, one NC, one EES, and one AELM.

Among them, AELM is a new journal, and there is no division yet. For the remaining eight articles, AEM, NC, and EES are all very good journals in the first district, while ACSAMI and JMCA are all journals in the first division of the major category and the second division of the minor category. Classified into the second district, that is, a total of four chapters in the second district and four chapters in the first district.

Xu Qiu downloaded the eight PDF files and sent them to the salesperson, saying, "There are four articles in the second section and four in the first section, all of which are from this year."

Sales: "OK, please provide the account number of the bank card and the branch where the bank card is opened."

Xu Qiu: "622848..., the Sub-branch of Shanghai University."

Sales: "After the information is verified, we will transfer the bonus to the bank card."

After finishing the chat with the salesperson, Xu Qiu turned his head, rubbed Han Jiaying's hair, and said, "Isn't this solved, and I can get a bonus of 6,000 yuan."

"Brother, aren't they afraid that someone will pretend to claim it?" Han Jiaying figured it out as soon as she said it, and then asked herself and answered: "We are all regular customers, our identities are basically clear, and every time we buy medicines, we have to pay for it." Go through the process of the drug warehouse, and then go to the school's financial office for reimbursement."

"That's right, the scientific research circle is so small, it's quite difficult to pretend to be a leader." Xu Qiu paused, and judged: "It is estimated that their company has increased a lot of business performance this year with a few articles from us, that's why they are so easy to talk about. And came up with this feedback activity.”

After a while, other small partners in the research group also appeared one after another.

Han Jiaying went to the water dispenser on the third floor to fetch water. Mo Wenlin saw the needle and leaned over to Xu Qiu: "Can you teach me how to analyze the article on the ternary blend system."

"Sure," Xu Qiu nodded. Although he doesn't do the ternary blend system himself, it is a small branch of organic photovoltaics after all, and he is quite familiar with it.

Xu Qiu talked eloquently: "There are three common ways of analysis.

First, it is light absorption complementary. Obviously, most systems will not choose a third component that coincides with the light absorption range of the binary system. What you add is PCBM and ITIC. With PCBM as the main body, you can say ITIC The addition of broadens the range of light absorption;

The second is the energy level structure, which usually forms cascading energy levels, that is, the energy level structure of the three components presents a stepped distribution. Your system is in the form of cascading energy levels, which can provide additional Charge transport channels, presence of energy transfer, etc.;

The third is the morphology of the blended film. By adjusting the blending ratio of the two receptor materials, the morphology of the blended film is optimized.

In addition to these general ideas, if two donors or two acceptors have similar properties, it can also be said that they form a donor/acceptor alloy, but if you are ITIC or PCBM, the performance gap is relatively large, so follow the previous three Just analyze the direction. "

"So that's how it is," Mo Wenlin wrote down what Xu Qiu said just now, and made a look of being stunned, and then pointed to a word on the Word, and said, "Then Xu Qiu, how should I do this?" .”

"This..." Xu Qiu just raised his head.

At this time, Han Jiaying suddenly coughed softly: "Wen Lin, I can do this too, let me teach you."

Mo Wenlin froze for a moment, then responded with a smile: "Okay, okay."

Han Jiaying sat down between Xu Qiu and Mo Wenlin, put down the water glass, and began to explain: "First...then...then...finally..., Wen Lin, get it."

Mo Wenlin smiled lightly and nodded, "Understood, I understand, Jiaying is really amazing."

Xu Qiu beside him couldn't help but sigh with emotion, the two of them are indeed good girlfriends, their relationship is really good.

After watching Han Jiaying and Mo Wenlin for a while, Xu Qiu was about to open Word and start writing his own articles, only to find that Wei Xingsi suddenly appeared at the door of 216: "Xu Qiu, have you read the recent documents, come and talk about them when you are free."

Xu Qiu had to bring more than a dozen documents to 218. Recently, only two papers on organic photovoltaics are worth noting, both of which are non-fullerene systems:

Xu Zhenghong and his group published a derivative of IDTBR on AM. By introducing a single fluorine atom on BT, IDTBR-F is obtained, but the efficiency has not reached a new high. The main selling point is the combination of P3HT donor material and IDTBR-F acceptor material, which has obtained an efficiency of 6.8%, and has a good Device stability is biased towards the concept of industrial applications.

Another article published on ACSAMI, although the grade of the article is average, the signal conveyed is worth noting. They imitated the previous IDT-ICIN of the senior sister, and synthesized a material of F8-ICIN, which has average photoelectric performance and an efficiency of only 5%.

It seems that other people have also begun to pay attention to the A unit of ICIN. I have to say that the action is really fast.

The literature lecture lasted more than half an hour, close to an hour.

After returning to the office, Chen Wanqing came to the door again: "Xu Qiu, the abstract of my IEICO system article has been written, please help me to have a look, okay?"

"Give me the USB flash drive." Xu Qiu replied, who made himself a second author, you must watch it, you can't push it.

After spending 20 minutes, Xu Qiu helped the senior sister to correct the summary, and also briefly modified the title, and then went to the bathroom to solve the physical problem.

Looking back, the breathing light of the mobile phone turned on. It turned out to be a message from Wu Shengnan: "I synthesize IDIC here, and I need to introduce alkyl side chains. I want to buy halogenated hydrocarbons and hexyl bromide. Can you help me buy them?"

Xu Qiu helped her place an order in the drug warehouse.

So, a morning passed, and Xu Qiu's own article did not change a single word.

PS: 3W8 is owed, 3W2 has been repaid, and there is still a difference of 6K.
